<a href='#toc'>Table of Contents</a><p>
<h2><a name='sect0' href='#toc0'>Name</a></h2>
auctl - control various audio server parameters
<h2><a name='sect1' href='#toc1'>Synopsys</a></h2>
<b>auctl</b> [-audio
<i>servername</i>] [-q] [<i>command...</i>]
<h2><a name='sect2' href='#toc2'>Description</a></h2>
The <i>auctl</i> program can be used to control
various audio server parameters. It is typically used when connecting up
new devices, or to set user preferences. If no command is specified on
the program command line, <i>auctl</i> reads commands from the standard output.
If the standard input and standard output are both attached to a terminal,
an interactive prompt is provided.
<h2><a name='sect3' href='#toc3'>Options</a></h2>
The following options may be used
with <i>auctl</i>:
<dl>
<dt><b>-audio </b><i>servername</i> </dt>
<dd>This option specifies the Network Audio System
server on which the files should be played. </dd>
<dt><b>-q</b> </dt>
<dd>This option indicates that
no prompt should be given when reading commands from the standard input.
</dd>
</dl>
<h2><a name='sect4' href='#toc4'>Commands</a></h2>
The following commands may be used with <i>auctl</i>:
<dl>
<dt><b>help</b> </dt>
<dd>This command
prints a list of the commands that may be given. </dd>
<dt><b>set device <i>id</i> gain [=,+,-]
<i>percent</i></b> </dt>
<dd>With <i>=</i>, this command sets the gain on the device specified by <i>id</i>
to the indicated percentage, or alters it by the given number of percentage
points if <i>+</i> or <i>-</i> is used. If the <i>id</i> is a decimal number <b>n</b>, the <i>nth</i> device
returned by the server (see <i>auinfo</i>) is used. Otherwise, <i>id</i> should be a
hexidecimal number specifying the resource identifier of the desired device.
</dd>
<dt><b>set device <i>id</i> linemode = low</b> </dt>
<dd>This command sets the linemode of the device
specified by <i>id</i> to the lower setting appropriate for microphones. </dd>
<dt><b>set device
<i>id</i> linemode = hi</b> </dt>
<dd>This command sets the linemode of the device specified
by <i>id</i> to the higher setting appropriate for CD players. </dd>
<dt><b>list device <i>id</i> gain</b>
</dt>
<dd>This command lists the gain of the specified device in the form needed
to set it. </dd>
<dt><b>list device <i>id</i> linemode</b> </dt>
<dd>This command lists the line mode of the
specified device in the form needed to set it. </dd>
<dt><b>list device <i>id</i></b> </dt>
<dd>This command
lists the gain and line mode of the specified device. </dd>
<dt><b>quit, exit, or ^D</b> </dt>
<dd>Either
of these commands or an end of file causes the program to exit. </dd>
</dl>
<h2><a name='sect5' href='#toc5'>Environment
Variables</a></h2>
<p>
The following environment variables are used by <i>auctl</i>:
<dl>
<dt><b>AUDIOSERVER</b>
</dt>
<dd>This specifies the name of default audio server to contact if no name is
explicitly given on the command line. </dd>
<dt><b>DISPLAY</b> </dt>
<dd>This specifies the name of
an X Window System display that should be assumed to also have a corresponding
Network Audio System server. </dd>
</dl>
